THOMAS H. BURRIDGE, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF HISRIGHT TO JAMES W. BUTCHER, OF SAME PLACE.

IMPROVEMENT lN AXLE-BOXES.

Specification forming part of Letters Patent No. 151,562, dated June 2,1874; application filed March 31, 1874.

To all whom it may concern Be it known that I, THOMAS H. BURRIDGE, ofSt. Louis, in the county of St. Louis and State of Missouri, haveinvented a certain Improved Automatic Oiler for Railway-(Jar Axles, ofwhich the following is a specification:

The first part of my invention relates to an oscillating greaser, whichis periodically immersed in the lubricant at the bottom of thegrease-box, preferably by the rotation of a cam connected to the axle bygearing, the grease-pad being raised by a counter-balance to bring it incontact with the axle as the depressing-cam is raised. The second partof my invention relates to the manner of attaching the axialv cog-pinionto the axle. In this the pinion is attached to an arm extending inwardfrom a circular strap or collar, which is fitted to surround the endcollar of the axle, and secured thereto by a screw, as shown.

In the drawings, Figure 1 is a top view of the greasing apparatus. Fig.2 is a side view of the end of an axle, with the collar and strap inaxial section. Fig. 3 is an end view of the apparatus. Fig. 4c is a sideview of the same with the grease-box in section.

A is the grease'box, which contains the axle-box, and slides in thepedestal of the cartruck. B is the axle, having a bearing, 0, in thejournal-box D. The end of the axle has the usual annular flange orcollar E, around which is secured the clip-collar F, having lugs f,through which passes a bolt, G, to tighten the clip-collar on the axle.The collar E has a circumferential groove, 0, to receive a rib, f,running around the interior of the clipstrap F. f is a transverse lug inthe strap, resting in a recess or key-seat in the collar to prevent theslip of the strap on the collar.

The above mode of attachment may be varied; for instance, lugs or studson. the strap F or collar E may enter recesses in the other, or screwsmay pass through the strap into the collar E.

H is an arm extending inward from the collar F to the center of theaxle, and to whose end is attached an axial pinion, h, or pinion in linewith the center of the axle. This pinion engages with a spur-wheel, I,having bearings on a pin, k, in a frame, K, secured to the inner side ofthe grease-box A by a foot, 70, resting on the bottom of the box, and abolt, L, passing into or through the side of the box. M and N arebearings of the rock-shaft O, to which is attached the oscillatingcarrier P of the grease-pad Q. The shaft 0 also carries an arm, R, whichis pressed down at each rotation of the wheel I by a cam, S, attached tosaid wheel. On the opposite side of the rockshat't to the grease-pad andlever is an arm carrying a counter-balance, T, of sufficient weight toraise the pad-carrier P and arm B after depression by the cam.

WVhen the grease-pad is raised, it is in contact with the lower side ofthe axle, as shown in Fig. 1, and when it is depressed it is immersedmore or less in the grease at the bottom of the box A.

The pad may be made, as shown, of loops of fibrous material hanging downso as to draw up and hold a portion of the lubricant by capillaryattraction; or a piece of fibrous cloth or felt may be attached to thetop of the carrier, and an edge of this may hang down for saturation; ormerely the top of the carrier may be covered with fibrous material, andits depression alone trusted to for saturation.

I claim as my invention- 1. In combination with the oil-box A and axleB, the oscillating carrier P and pad Q, as and for the purpose setforth.

2. The oscillating carrier P, grease-pad Q, bearings M N,counter-balance T, spur-wheel I, pinion h, arm R, and cam S, incombination with the grease-box A and axle B, substantially as and forthe purpose set forth.

3. In combination with the axle-collar E, the clip-collar F, having armH, carrying an axial pinion, h, substantially as set forth.
